V-Box for Fibo 90cm?

[johnsattuk]

Trouble is, I don't have the facilities to do any machining at all...but I can mod a PCB. I see you've had a look inside the alsat/powertech 500, do you reckon I could tap 5v somewhere?

I've had a look in several different models and they all seem to use the same motherboard, so I guess you will be able to find a 5v supply.
I prefer to use a reed sw., one less wire to run, bit less power to supply, more reliable.
I can help with reed sw, mod if required

Hi!
if ,i remeber right,not every vbox "clone" using the same remote code,some is difrent from the orginal!

OK, I bought the Alsat/Powertech, as that seems to be the most capable Vbox, and I like the 6 digit readout and overload protection. The motherboard seems to be different from the others I've seen photographed. To start, it's in 2 pieces and doesn't have the large plug in IC. The RF board is of a type I've seen criticized in some threads.

Not impressed by the build quality and if I'd paid the full retail price, I would not be happy.

I noticed that there are 2 blanked off ports on the rear panel. Could these originally have been for 5 volts?

I want to get the Fibo working this weekend, so would it be OK to use any 5 volt supply for now? The reason I ask is that I have seen a thread in which someone claims that just such a supply burnt out their optocoupler, because the 5V should only be present while the dish is turning.

John, I think I will take up your kind offer of help with the reed switch mod. How do I go about this?

Why change the Fibo motor??????

Its so simple to take 5 Volts out of the VBox.
I have do this for manny users and no one have a problem the VBox can run on this way verry simple and also manny years.

Look at my site there is a complete workshop how to change it.

Its in DUtch but with a google langue page simple to translate.

It's a different vbox Snuffer, look at the photographs. I had a look at your site.

Simpel every box named what you will have the 2 relais black boxes also yours i see on the Photo.
Arround that you will find also a 5 Volts piont (best to search around a resistor) Take this for your 5 Volt and test perhaps he switch of the 5 volts and meseure the resitor of the V is drop down if yes remove this resistor and thats it.

Do you have a circuit diagram of it??

Good luck

 

[joekir]

No circuit Ron and very unlikely to be able to get one. Lets just say that the distribution of this product has some...limitations. But, so that I can get the Fibo up at least, is it safe to use a 5V supply from an adaptor?

 

[Snuffer]

Yes you can use the 5 volt from a adapter no piont bult hem inside the vbox you have 5 volts are continius there.
